The most accurate way to determine any bikeís weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All Giant bikes are designed for best-in-class weight and ride quality.

XC Tuned Geometry:
More acute (69-degree headtube angle) geometry, optimized for a shorter-travel (100mm) suspension fork, delivers a performance-oriented ride for aspiring XC riders.

Compliance Tuned:
The rear end of the frame features a lowered seatstay design for added compliance, resulting in a smoother ride and added control on rough trails.


Features: Giantís original oversized fork steerer-tube technology. Designed to provide solid front-end steering performance, the systemís oversized headset bearings and tapered steerer tube provide optimal steering stiffness. Road models feature 1 1/8-inch top and 1 1/4-inch bottom bearings, while the mountain version features 1 1/8-inch top and 1 1/2-inch bottom bearings.

Benefit: OverDrive provides up to 15 percent more torsional steering stiffness than straight steerer-tube designs. This translates into much more accurate steering input from a riderís hands, through the handlebar and stem, and down to the front wheel. Whether hammering uphill or carving through a corner, OverDrive transmits input directly to the front wheel for more precise handling.
